Semrock Inc. has announced the EdgeBasic long-wave pass filters, a line of hard-coated optical devices with a typical transmission of 98 percent and a laser-line blocking optical density of >6. Housed in a labeled black anodized aluminum ring with a 25-mm diameter and 3.5-mm thickness, they are available for nominal laser wavelengths of 488, 532, 635 and 785 nm. The filters have an edge steepness tailored for cost-sensitive application-specific Raman systems and for fluorescence imaging. They are backed by a five-year warranty.
